[Adjuvant surgical maneuvers in penile prostheses implant to improve their aesthetic and functional outcomes]. / Maniobras quirúrgicas adyuvantes en el implante de prótesis de pene para mejorar su resultado estético y funcional.

Penile prosthetic surgery is the definitive treatment for those patients with erectile dysfunction refractory to medical treatment. Although it associates satisfaction rates>90%, it is known that men with Peyronie's disease, body mass index>30kg/m2 or those previously operated on radical prostatectomy have lower satisfaction rates than the general population. The main reasons for dissatisfaction are the subjective loss of penile length and glans' flaccidity. Given such circumstance, several adjuvant surgical techniques have been described to improve aesthetic and functional outcomes after the implant. In our review, we wanted to investigate the different maneuvers used in patients with Peyronie's disease, those used to avoid the reduction of penile length and those used to avoid the floppy glans syndrome.

The Learning Curve for Robot-assisted Partial Nephrectomy: Impact of Surgical Experience on Perioperative Outcomes.

Robot-assisted partial nephrectomy (RAPN) outcomes might be importantly affected by increasing surgical experience (EXP). The aim of the study is to investigate the effect of EXP on warm ischemia time (WIT), presence of at least one Clavien-Dindo ≥2 postoperative complication (CD ≥ 2), and positive surgical margins (PSMs) to define the learning curve for RAPN. We evaluated 457 consecutive patients diagnosed with a cT1-T2 renal mass were evaluated. EXP was defined as the total number of RAPNs performed by each surgeon before each patient's operation. Median WIT was 14min and the rate of CD ≥ 2 and PSMs was 15% and 4%, respectively. At multivariable regression analyses adjusted for case mix, EXP resulted associated with shorter WIT (p<0.0001) and higher probability of CD ≥ 2-free postoperative course (p=0.001), but not with PSMs (p=0.7). The relationship between EXP and WIT emerged as nonlinear, with a steep slope reduction within the first 100 cases and a plateau observed after 150 cases. Conversely, the relationship between EXP and CD ≥ 2-free course resulted linear, without reaching a plateau, even after 300 cases. Patient summary: Perioperative outcomes after robot-assisted partial nephrectomy (RAPN) are importantly and individually affected by surgeon's experience. After 150 RAPNs, no further improvement is observed with respect to ischemia time, but the learning curve appears endless with respect to complications.
